Seatalk network to PC running Time Zero

[Gerrycooper56]

Hi, I have a reasonably new Raymarine network using seatalk nag with plotter, ais, wind, depth, autopilot. The plotter is a newer C125 with wifi built in. I also have TimeZero Navigator running on a PC, connected to the network via a serial cable. Since running a lighthouse update the data to the PC has stopped. I changed the serial to USB convert or but no change. Is there a box that plugs into the seatalk ng terminal block and outputs network data in NMEA format to USB? Since the original method of data transfer stopped for some reason I have since taken the ais USB output and connected that to the PC - it works but only gives the ais data so am missing the depth and wind speed. Please advise the best (most reliable way to get the network data to the USB on the PC. I have read about the E85001 interface but when searching on the Raymarine website doesn't appear.

Thanks
